Application filed February 6, 1914, Serial No. 816,928. Renewed. April 21, 1916. Serial No. 92,761.

To all whom it may concern:

Be it known that I, HENRY N. HARPER, a citizen of the United States, and-a resident of Huston, in the parish of Lincoln and State of Louisiana, have invented a new and useful Improvement in Irrigators, of which the following is a specification.

My invention is an improvement in irrigators, and has for its object to provide a device of the character specified, capable of connection to a receptacle and arranged to be held in a central position with respect to the receptacle and in position to be engaged and to be held engaged without requiring attention from the user and leaving the hands of the user free.

In the drawings :Figure 1 is a perspective view of the improved irrigator, Fig. 2 is a section on the line 2-2 of Fig. 3, looking in the direction of the arrows, Fig. 3 is an enlarged top plan view of a portion of the mechanism shown in Fig. 1, and Fig. 4L is a side view of the discharge tube and its support with the distending device removed.

The present embodiment of the invention is .shown in connection with a receptacle 1 of any suitable material, the said receptacle having an open top 2, as shown, and the top of the receptacle is beaded or rounded, as shown at 3 to prevent injury to the person of the user.

The improvement comprises a substantially conical disk 4 of suitable material, as for instance, hard rubber or the llke, the said disk having a central opening 5, and the disk is provided with a nipple 6 at the lower end of the opening, the said nlpple being externally roughened or corrugated for engagement by one end of a flexible.

tube 7 The disk 4 is arranged w1th 1ts apex upward, and the central portion of the disk is of greater thickness than the peripheral portion thereof, as indlcated at 8, so that an annular shoulder 9 is formed between the thickened portion and the peripheral portion, and the said shoulder is threaded as shown in Figs. 2 and 4t.

At the thickened portion, the d 1sk is provided with an opening 10, the said opening extending entirely through the ClIS k. The opening 5 is at the apex of the d1sk, and the upper end of the said opening is counterbored or enlarged as shown at 11, to form a socket for receiving the lower endof a dlscharge nozzle 12. The said lower end of the discharge nozzle is shaped to fit within the counterbored portion of the opening, and

I the upper end of the nozzle is enlarged, and

is of olive shape as shown. A plurality of nozzles is provided for different uses, thenozzle 12 shown in: Fig. 2, having a series of openings 13 at the enlarged rounded end, wlnle the nozzle 12 shown in Fig. 4, is similar in all respects to the nozzle 12, ex-

cept that it is provided in the rounded end 17 is arranged on the under face of each strap, the screws being passed through the reinforcing plate and through the end of the strap, and into threaded openings 18 in the disk.

The plate 1'? is counterbored or reamed,

so that the heads of the screws are flush with the under face of the plate. The connection between the strapsand the disk is as before stated, on the under face of the disk, and at such a point that the said screws and plate will not be below the level of the under face of the supporting straps 15.

Each strap is provided at its outer end with a loop 19, and each loop is engaged by a loop 20 of a hook 21. The outer ends of the straps are doubled back upon themselves after being passed through the loops 19 of the hooks, and the hooks are arranged to engage the beaded or rounded portions of the upper end of the receptacle.

The disk is provided with three straps as shown, the said straps being spaced at equal distances from each other, and the straps are of such length that the disk is supported at the center of the top of the receptacle.

In certain uses, it is desirable to use the discharge tube with a distending device so arranged that an outlet is permitted for the solution entering through the nozzle. The said device 22, shown in Figs. 1 and 2, is approximately frusto-conical in shape, and is provided with a central openlng 23 of suflicient' diameter to receive the nozzles 12 and 12 and to leave an annular space bethe upper tween the said nozzles and the inner surface of the said device as shown in Fig. 2.

v The distending device is arranged with its large end downward, and the said large end is shaped to fit the upper face of the disk outside of the threaded shoulder 9. The

.opening 23 of the distending device is enlarged near its lower end as shown at 24, the enlargement being of such diameter that when the device is in place on the disk, end of the opening 10 will be uncovered and will open into the enlarged portion 24 of the bore.

Below the enlargement 24: of the bore or opening 23, the distending device is again enlarged to fit around the shoulder 9 and at this point the said bore is threaded as shown at 25 to engage the threaded shoulder 9 of the disk. The arrangement is such that when the distending device is in place, the opening 10 may communicate with the bore 23 of the distending device and the lower end or base of the said distending device will fit closely against the upper face of the disk outside the shoulder 9 to form a fluid tight joint. The upper end of the distending device is rounded to prevent injury to the user, and the said upper end is spaced below the olive shaped portion of the discharge tube. V

In operation, a suitable receptacle for the solution to be injected is connected with the end of the tube 7 remote from the disk, and the said receptacle is elevated so that the solution will discharge through the openings 13, 14: of the discharge tube used. With the discharge tube 12, the solution may pass out by way of the space between the discharge tube'and the interior of the distending device, the said device retaining the parts distended to permit this outward flow.

The solution passes through the opening 10 into the receptacle.

It is not desired to permit the solution to discharge at once, the discharge tube 12* is used, and the distending device is omitted. The improvement consists in efiect of a support having an opening provided at its lower end with means for engagement by a supply tube and at its upper end with a socket for engagement by a discharge tube, together with a cone-shaped or tubular distending device detachably engaging the sup-e port coaxial with the central openlng and interchangeable discharge tubes for connection with the support and having means for engaging the socket, each of the said tubes passing through the distending device.

It is obvious that the disk maybe connected with any suitable receptacle or receiver, or the said device may be used without the receptacle, if desired. The discharge tubes 12 and 12 may be of any desired shape and size, depending upon the purpose for which they are to be used and they may be enlarged and of any suitable material, as may also the distending device 22. The said device may also be made of different sizes.

With the improved device, the hands of the user are free, and since the device is yieldingly supported, there can be no injury to the user. All of the elements of the device may be easily cleaned after use, and when separated access may be had to all of the interior of the different parts. The opening 10 being of less capacity than the discharge tube, the solution may be dammed up or held in the cavity if desired.

The straps 15 are preferably of elastic material, in order that they may yield and in order that they may stretch or contract to permit the device to be attached to different sized receptacles. The device is especially adapted for attachment to slop jars.
